Struct rustc_middle::mir::VarDebugInfoFragment

pub struct VarDebugInfoFragment<'tcx> {
    pub ty: Ty<'tcx>,
    pub projection: Vec<PlaceElem<'tcx>>,
}

Fields

ty: Ty<'tcx>

Type of the original user variable. This cannot contain a union or an enum.

projection: Vec<PlaceElem<'tcx>>

Where in the composite user variable this fragment is, represented as a “projection” into the composite variable. At lower levels, this corresponds to a byte/bit range.

This can only contain PlaceElem::Field.

Trait Implementations

impl<'tcx> Clone for VarDebugInfoFragment<'tcx>

fn clone(&self) -> VarDebugInfoFragment<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for VarDebugInfoFragment<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx, __D: TyDecoder<I = TyCtxt<'tcx>>> Decodable<__D> for VarDebugInfoFragment<'tcx>

fn decode(__decoder: &mut __D) -> Self

impl<'tcx, __E: TyEncoder<I = TyCtxt<'tcx>>> Encodable<__E> for VarDebugInfoFragment<'tcx>

fn encode(&self, __encoder: &mut __E)

impl<'tcx, '__ctx> HashStable<StableHashingContext<'__ctx>> for VarDebugInfoFragment<'tcx>

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher )

impl<'tcx> TypeFoldable<TyCtxt<'tcx>> for VarDebugInfoFragment<'tcx>

fn try_fold_with<__F: FallibleTypeFolder<TyCtxt<'tcx>>>( self, __folder: &mut __F ) -> Result<Self, __F::Error>

The entry point for folding. To fold a value t with a folder f call: t.try_fold_with(f).

fn fold_with<F>(self, folder: &mut F) -> Self

where F: TypeFolder<I>,

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.

impl<'tcx> TypeVisitable<TyCtxt<'tcx>> for VarDebugInfoFragment<'tcx>

fn visit_with<__V: TypeVisitor<TyCtxt<'tcx>>>( &self, __visitor: &mut __V ) -> __V::Result

The entry point for visiting. To visit a value t with a visitor v call: t.visit_with(v).

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
